Title: Inductive proximity switch
Inventor: KARISCH MICHAEL DIPL ING
IPC: H03K17/95
Filed: 1993-11-25
Granted: 1995-04-13
Abstract: The invention relates to an inductive proximity switch having an inductive presence indicator which can be influenced from outside, with a switched-mode amplifier following the presence indicator and with an electronic switch, for example a transistor, a thyristor or a triac, which can be controlled by the presence indicator via the switched-mode amplifier, the presence indicator having an indicator resonant circuit (1) with an indicator coil (2) and a compensation resonant circuit (3) with a compensation coil (4) which is wound in the opposite direction from the indicator coil (2), and the indicator resonant circuit (1) and the compensation resonant circuit (3) being connected in series. According to the invention, a high independence from external fields, in conjunction with a high sensitivity, is achieved by the fact that the presence indicator exhibits a pot-type ferromagnetic core (5), that the indicator coil (2) is arranged on the open side of the pot-type ferromagnetic core (5) and that the compensation coil (4) is arranged in the pot-type ferromagnetic core (5) underneath the indicator coil (2). <IMAGE>

Abstract: FIELD: construction. SUBSTANCE: tubular filling pile erection method incorporates tubular core driving into the soil with artificial consolidation of the soil plug; erection of annular well, core extraction, and well filling with concrete mix under vibration action. The core is driven in without artificial consolidation of the soil plug; the concrete mix after casting and till the core extraction is pressed into the well walls by the means of tubular vibrostamp which moves along the core. The vibrostamp interacting during the working stroke with the core produces annular air-filled cavity. Then the soil plug humidity is regulated and brought to nearly optimal value. The artificial plug soil consolidation is effected under the vibration action created by vibration core extraction which is carried out in conjunction with and slightly ahead of the vibrostamp extraction. Furthermore, coincidentally with the concrete mix pressing, as soon as the vibrostamp is plunged in, the vacuuming is accomplished through isolating of annular cavity and pumping out of it the air. Then the vibroconsolidation and moistening of the plug soil begins. The moistening is realized successively from bottom to top by injecting required quantity of liquid under pressure into the soil of the plug through the gap between the vibrostamp and the core in the bottom part of the air-filled cavity. The plug soil humidity reduction is effected through surface vacuuming coincidentally with concrete mix vacuuming. The extracted water is removed outside the erected pile. EFFECT: improved erection technology. 5 cl, 4 dwg

Abstract: FIELD: cleaning gases. SUBSTANCE: in absorption column waste gases are brought into continuous contact with a water absorbent containing magnesium hydroxide, the absorbent being circulated in the column. Both water absorbent and the absorption product are removed from the bottom of the column and fed into a recovery system. The recovery process includes a two-stage neutralization step followed by a separation step for separating product into a liquid and a solid phases. At the first neutralization step a water slime is utilized as an aid substance produced by separation of the solid phase. The absorbent is partially neutralized. After being partially neutralized, the absorbent is fed to the second stage, at which a roasted, light and finely divided magnesium oxide is utilized as an neutralizing agent. The separated liquid phase, free from solid particles, is supplied to the column as an absorption solution. Prior to being supplied to the first neutralization stage at least a portion of the water slime is preferably wet pulverized at a mill. No incrustation is observed on the gas cleaning equipment. The final concentration of sulfur oxide is ten parts per million. EFFECT: improved quality of gas cleaning. 2 cl, 1 dwg

IPC: G01N23/227
Filed: 1991-07-15
Granted: 1994-02-28
Abstract: FIELD: determination of physical and chemical properties of metals and alloys. SUBSTANCE: after vacuum heat treatment metals M 1  and M 2  are placed in reservoirs 1 and 2, and the charging hoppers are unsoldered along lines A-A and B-B. Then the device proper is unsoldered from the exhaust unit and placed inside the air thermostat allowing the device to be fixed in any position in the space. To measure the electronic work function of component M 1 , the device is turned clockwise through an angle of approximately 90 ≃ 90 ° , and part of metal is poured off into measuring compartment 4. When the device returns to the initial position, metal from measuring compartment 4 through tube 14 runs off down-wards and drops out into upper sleeve 7 flooding the lower ends of cathode 11 and glass pocket 12 with thermocouple 13. Measuring compartment 4 provides for a constant volume of liquid melt 8 delivered to upper sleeve 7, i. e. a constant level of melt, and, consequently, a constant depth of submersion of the thermocouple. To measure the electronic work function of alloy, part of liquid metal M 2  is poured off from reservoir 2 by turning the device "towards yourself" through a definite angle in the plane perpendicular to the sheet plane, into U-shaped proportioner 3, whose volume is graduated relative to the marks. Having noticed the level of metal in the U-shaped tube, the device is turned "from yourself" beyond the sheet plane and the known amount of metal M 2  is added to metal M 1 , i. e. an alloy of the known composition is formed. Transfer of the alloy to upper sleeve 7 for measuring the electronic work function is effected in the same way as for metal M 1 . EFFECT: facilitated procedure. 3 dwg

Granted: 1994-07-30
Abstract: FIELD: measurement technology. SUBSTANCE: sensor has two stationary ferromagnetic cores, two movable anchors and two pairs of inductive windings, connected according to a bridge circuit. Movable anchors are made as hollow ferromagnetic cylinders, on the butts of which nonmagnetic ring-shaped overlappings accordingly are fixed to make a current-vortex effect. The sensor's anchors have located in their middle inner bead and outer bead with similar diameter sizes, as stationary ferromagnetic cores have. During shift of any of anchors from their neutral position, balance of the bridge circuit, that was formed by two pairs of windings, is broken due to change of their inductive resistance. As a result of it a signal, proportional to algebraic sum of two controlled objects, appears on output of the bridge circuit. EFFECT: increase of sensitivity and expansion of functional capabilities of inductive sensor of linear movements. 2 cl, 5 dwg
